Ethernet Local Management Interface at a Provider Edge

First Published: February 27, 2007

Last Updated: March 2, 2007

The advent of Ethernet as a metropolitan-area network (MAN) and WAN technology imposes a new set of operations, administration, and management (OAM) requirements on Ethernet's traditional operations, which had been centered on enterprise networks only. The expansion of Ethernet technology into the domain of service providers, where networks are substantially larger and more complex than enterprise networks and the user-base is wider, makes operational management of link uptime crucial. More importantly, the timeliness in isolating and responding to a failure becomes mandatory for normal day-to-day operations, and OAM translates directly to the competitiveness of the service provider.

This module provides general information about configuring Ethernet Local Management Interface (LMI), an OAM protocol, on a provider edge (PE) device.

Prerequisites for Ethernet Local Management Interface at a Provider Edge

•Ethernet OAM must be operational in the network.

•For Ethernet OAM to operate, the PE side of a connection must be running Ethernet Connectivity Fault Management (CFM) and Ethernet LMI.

•All VLANs used on a PE device to connect to a customer edge (CE) device must also be created on that CE device.

Restrictions for Ethernet Local Management Interface at a Provider Edge

•Ethernet LMI is not supported on routed ports, EtherChannel port channels, or ports that belong to an EtherChannel, private VLAN ports, IEEE 802.1Q tunnel ports, or Ethernet over Multiprotocol Label Switching (MPLS) ports.

•Ethernet LMI cannot be configured on VLAN interfaces.

Information About Ethernet Local Management Interface at a Provider Edge

To configure Ethernet LMI on a PE device, you should understand the following concepts:

•Ethernet Virtual Circuit

•Ethernet LMI

•Ethernet CFM

•OAM Manager

•Benefits of Ethernet LMI at a Provider Edge

Ethernet Virtual Circuit

An Ethernet virtual circuit (EVC) as defined by the Metro Ethernet Forum is a port level point-to-point or multipoint-to-multipoint Layer 2 circuit. EVC status can be used by a CE device to find an alternative path in to the service provider network or in some cases, fall back to a backup path over Ethernet or another alternative service such as Frame Relay or ATM.

Ethernet LMI

Ethernet LMI is an Ethernet OAM protocol between a CE device and a PE device. Ethernet LMI provides CE devices with the status of EVCs for large Ethernet MANs and WANs and provides information that enables CE devices to autoconfigure. Specifically, Ethernet LMI runs on the PE-CE user network interface (UNI) link and notifies a CE device of the operating state of an EVC and the time when an EVC is added or deleted. Ethernet LMI also communicates the attributes of an EVC.

Ethernet LMI interoperates with Ethernet CFM, an OAM protocol that runs within the provider network to collect OAM status. Ethernet CFM runs at the provider maintenance level (user provider edge [UPE] to UPE at the UNI). Ethernet LMI relies on the OAM Ethernet Infrastructure (EI) to interwork with CFM to learn the end-to-end status of EVCs across CFM domains.

Ethernet LMI is disabled globally by default. When Ethernet LMI is enabled globally, all interfaces are automatically enabled. Ethernet LMI can also be enabled or disabled at the interface to override the global configuration. The last Ethernet LMI command issued is the command that has precedence. No EVCs, Ethernet service instances, or UNIs are defined, and the UNI bundling service is bundling with multiplexing.

Ethernet CFM

Ethernet CFM is an end-to-end per-service-instance (per VLAN) Ethernet layer OAM protocol that includes proactive connectivity monitoring, fault verification, and fault isolation. End-to-end CFM can be from PE device to PE device or from CE device to CE device. For more information about Ethernet CFM, see Ethernet Connectivity Fault Management.

OAM Manager

The OAM manager is an infrastructure element that streamlines interaction between OAM protocols. The OAM manager requires two interworking OAM protocols, in this case, Ethernet CFM and Ethernet LMI. No interactions are required between Ethernet LMI and the OAM manager on the CE side. On the UPE side, the OAM manager defines an abstraction layer that relays data collected from Ethernet CFM to the Ethernet LMI device.

Ethernet LMI and OAM manager interaction is unidirectional, from the OAM manager to Ethernet LMI on the UPE side of the device. An information exchange results from an Ethernet LMI request or is triggered by the OAM manager when it receives notification from the OAM protocol that the number of UNIs has changed. A change in the number of UNIs may cause a change in EVC status.

The OAM manager calculates EVC status given the number of active UNIs and the total number of associated UNIs. You must configure CFM to notify the OAM manager of all changes to the number of active UNIs or to the remote UNI ID for a given service provider VLAN (S-VLAN) domain.

The information exchanged includes the following:

•EVC name and availability status (active, inactive, partially active, or not defined)

•Remote UNI name and status (up, disconnected, administratively down, excessive frame check sequence [FCS] failures, or not reachable)

•Remote UNI counts (the total number of expected UNIs and the number of active UNIs)

Benefits of Ethernet LMI at a Provider Edge

Ethernet LMI on a PE device provides the following benefits:

•Communication of end-to-end status of the EVC to the CE device

•Communication of EVC and UNI attributes to a CE device

•Competitive advantage for service providers

How to Configure Ethernet Local Management Interface at a Provider Edge

Perform the following tasks to configure Ethernet LMI on a PE device.

•Configuring Ethernet LMI Interaction with CFM, page 4

•Displaying Ethernet LMI and OAM Manager Information

Ethernet LMI Interaction with CFM

For Ethernet LMI to function with CFM, you must configure EVCs, Ethernet service instances, and Ethernet LMI customer VLAN mapping. Most of the configuration occurs on the PE device on the interfaces connected to the CE. On the CE device, you need only enable Ethernet LMI on the connecting interface. Also, you must configure some OAM parameters; for example, EVC definitions on PE devices on both sides of a metro network.

CFM and OAM interworking requires an inward facing MEP.

Configuring the OAM Manager

Note If you configure, change, or remove a UNI service type, EVC, Ethernet service instance, or CE-VLAN configuration, all configurations are checked to ensure that the configurations match (UNI service type with EVC or Ethernet service instance and CE-VLAN configuration). The configuration is rejected if the configurations do not match.

Perform this task to configure the OAM manager on a PE device.

Modification

12.2(25)SEG

This command was introduced.

12.2(33)SRB

This command was implemented on the Cisco 7600 series routers.

Usage Guidelines

UNI options determine the functionality that the interface has regarding bundling VLANs and multiplexing EVCs.

If you want only the bundling or only the multiplexing service, you must configure the service appropriately. Bundling supports only one EVC at the UNI with one or multiple customer edge (CE)-VLAN IDs mapped to the EVC.

When multiplexing is configured, the UNI can have one or more EVCs with a single CE-VLAN ID mapped to each EVC.

When you configure a UNI ID on a port, that ID is used as the default name for all maintenance end points (MEPs) configured on the port.

You must enter the ethernet uni command with the id keyword and id argument on all ports that are directly connected to CE devices. When the specified ID is not unique on a device, an error message is displayed.

When you configure, change, or remove a UNI service type, the EVC and CE-VLAN ID configurations are checked to ensure that the configurations and the UNI service types match. If the configurations do not match, the command is rejected.

Examples

The following example shows how to configure bundling without multiplexing:
Router(config)# interface ethernet 2/1
Router(config-if)# ethernet uni bundle
This example shows how to identify a UNI as test2:
Router(config)# interface ethernet 2/1
Router(config-if)# ethernet uni id test2

Command History

Release

Modification

12.2(25)SEG

This command was introduced.

12.2(33)SRB

This command was implemented on the Cisco 7600 series routers.

Usage Guidelines

The UNI count determines the type of service in the EVC.

•A UNI count value of 1 or 2—The service defaults to point-to-point service.

•A UNI value of 2—You can leave the service at the default or you can configure point-to-multipoint service by entering the multipoint keyword.

•A UNI value of 3 or greater—The service is point-to-multipoint.

You should know the correct number of maintenance end points (MEPs) in the domain. If you enter a UNI count value greater than the number of endpoints, the UNI status shows as partially active even if all endpoints are up. If you enter a UNI count less than the number of endpoints, UNI status shows as active, even if all endpoints are not up.

Caution Configuring a UNI count does not prevent you from configuring more endpoints than the configured number of UNIs. For example, if you configure a UNI count of 5, but you create 10 MEPs, any 5 MEPs in the domain can go down without the status changing to partially active.

Examples

The following example shows how to set a UNI count of 2 with point-to-multipoint service:
Router(config)# ethernet evc test1
Router(config-evc)# uni count 2 multipoint

Ethernet Local Management Interface at a Provider Edge

12.2(33)SRB

Ethernet LMI is an Ethernet OAM protocol between a CE device and a PE device. Ethernet LMI provides CE devices with the status of EVCs for large Ethernet MANs and WANs and provides information that enables CE devices to autoconfigure. Specifically, Ethernet LMI runs on the PE-CE UNI link and notifies a CE device of the operating state of an EVC and when an EVC is added or deleted. Ethernet LMI also communicates the attributes of an EVC.

In Cisco IOS Release 12.2(33)SRB, this feature was introduced on the Cisco 7600 series router.

Table 4 Feature Information for Ethernet Local Management Interface at a Provider Edge
Feature Name	Releases	Feature Information
Ethernet Local Management Interface at a Provider Edge	12.2(33)SRB	Ethernet LMI is an Ethernet OAM protocol between a CE device and a PE device. Ethernet LMI provides CE devices with the status of EVCs for large Ethernet MANs and WANs and provides information that enables CE devices to autoconfigure. Specifically, Ethernet LMI runs on the PE-CE UNI link and notifies a CE device of the operating state of an EVC and when an EVC is added or deleted. Ethernet LMI also communicates the attributes of an EVC. In Cisco IOS Release 12.2(33)SRB, this feature was introduced on the Cisco 7600 series router.
